Project description:Interventions: Group 1: We want to evaluate the frequency of a family history of colorectal cancer (CRC) and advanced adenomas in 40-54 year old persons in a general practitioner (GP) setting and identify the variables (e.g. demographic, genetic, epigenetic and proteomic biomarkers) that are associated with it. In addition, we want to detect informed decision, anxiety and regret with respect to screening. The health care assistant in the general practice will contact eligible patients and complete the Network against colorectal cancer questionnaire. For those who have a positive family history the GP will provide family members related to CRC patients with adequate evidence-based information and describe prevention strategies. We plan to examine the participant´s family history of CRC in detail and further variables (e.g. demographics) associated with an increased risk will be collected. Additional stool and blood samples will be collected from study-participants who decide to undergo a colonoscopy (n~350) and analyzed in the German Cancer Research Center (DKZF) Heidelberg to see whether further relevant variables are associated with an increased risk of CRC
We expect that about 8,750 person in 50 general practices in Hesse will be asked, of those about 875 are expected to have a positive family history of colorectal cancer. Of those, we expect around 350 persons to follow the invitation to have a colonoscopy.
Primary outcome(s): Frequency of a family history of (colorectal) cancer and advanced adenomas in a GP setting

Project description:Conflicting guideline recommendations for screening colonoscopy result due to scant data upon which to develop appropriate recommendations. No previous study has compared the prevalence of advanced adenomas or adenomas (any size) among 40-49 year old individuals with a first degree relative (FDR) with colorectal cancer (CRC) versus 40-49 year old average risk individuals with no family history of CRC. The purpose of this study is to determine the prevalence of colon adenomas in 40-49 year old individuals and identify risk factors associated with the presence of advanced adenomas. This data will provide evidence to determine appropriate colon cancer screening guidelines in 40-49 year old persons with a family history of colon polyps or colorectal cancer.

Project description:A complete family history (FH) may identify persons at high risk for certain conditions. They can be offered genetic testing and life-saving screening and treatment. In practice, complete FH is rarely collected or entered into the electronic medical record (EMR). The Family History Screening Questionnaire is a survey patients complete to tell whether they are at increased risk of specific cancers, heart disease or diabetes. We will test a new way to record FH that includes an app to improve use of FH by family physicians and patients. The strategy includes education for patients and physicians about the importance of FH; patient completion of the FH questionnaire prior to appointments; and prompts in the EMR. We expect this to help family physicians and patients interpret FH and make the best decisions. We will assess the proportion of patients with new EMR FH information. We will explore if the strategy increases appropriate referrals for screening and genetic consultation for those at increased FH risk. We will also obtain patients’ and physicians’ feedback on this strategy. This new approach may improve FH information exchange between patients and physicians, encourage shared decision-making and reduce cancer deaths and chronic disease burden.

Project description:Fecal immunochemical tests (FIT) detecting hemoglobin in stool are widely used for non-invasive colorectal cancer (CRC) screening, but their sensitivity leaves room for improvement. Our aim is to identify novel protein biomarkers in stool that outperform or complement hemoglobin in detecting CRCs and advanced adenomas (AAs). Stool samples (one series of 12 CRCs and 10 controls, and a second series of 81 CRCs, 40 AAs, 43 non-advanced adenomas and 129 controls) were analyzed by mass-spectrometry and searched for human proteins. Classification and regression tree and logistic regression analyses were performed to identify protein combinations that differentiated CRCs and/or AAs from controls. Antibody-based assays for four selected proteins were performed on an independent series of FIT samples (14 CRCs, 16 AAs, 18 non-advanced adenomas and 24 controls) Results: In total, 834 human proteins were identified, of which 29 were significantly enriched in CRCs versus controls in both stool sample series. Combinations of four proteins reached sensitivities of 80% and 45% for detecting CRCs and AAs, at 95% specificity, which was higher than hemoglobin alone.

Project description:Interventions: Group 1: Persons without family history of colorectal cancer: to fill out online-questionnaire
Group 2: Persons with family history of colorectal cancer: to fill out online-questionnaire, take part in consultation regarding colorectal cancer prevention and donate the biosamples
Primary outcome(s): The aims of the RaPS study are:
1. To provide the necessary empirical evidence for the design and implementation of efficient risk adapted CRC (colorectal cancer) screening strategies among the high risk group of people with family history of CRC.
2. To identify and evaluate novel biomarkers for noninvasive risk stratification and early detection of CRC and its precursors among people with family history of CRC.

Project description:Formalin-fixed, paraffin-embedded samples from 27 FIT interval CRC and 54 screen-detected CRCs collected in a pilot-program of FIT-based CRC screening in the southwest and northwest regions in the Netherlands, were used in this study. DNA was extracted for 1) Shallow Sequencing (copy number analysis) and 2) TSACP Amplicon Cancer Gene Panel (mutations) of 22 FIT Interval CRCs and 45 screen-detected CRCs.

Project description:Colorectal cancer (CRC) poses one of the most serious threat against human health worldwide, and abnormally expressed c-Myc and p53 are deemed the pivotal driving forces of CRC progression. Here we discovered a lncRNA FIT, which was down-regulated in CRC clinical samples, was transcriptionally suppressed by c-Myc and promoted CRC cells apoptosis by inducing FAS expression. FAS is a p53 target gene, and we found that FIT formed a trimer with RBBP7 and p53 which facilitated p53 acetylation and transcription. Moreover, FIT was capable of retarding CRC growth in mice xenograft model and positively relevant to FAS expression clinically. Thereby our study elucidated the role of lncRNA FIT in human colorectal cancer growth and provides a potential target for anti-CRC drugs.

Project description:Family health history can help identify patients at higher than average risk for disease. There is no standardized system for collecting and updating family health history, using this information to determine a patient’s disease risk level, and providing screening recommendations to patients and providers. Patients will enter their family health history into MeTree, a family history software program. The program will produce screening recommendations tailored to the patient’s family health history. The investigators will examine whether this process increases physician referrals for, and patient uptake of, guideline-recommended screening for colorectal cancer.

Project description:There are ~1.4 million cases of colorectal cancer (CRC) annually worldwide. Due to recent implementation of bowel cancer screening (BCS), incidence of diagnosis with stage I (T1/2, N0, M0) CRC has increased nearly four-fold; from approximately 12% pre-screening to approximately 42-45%. While survival rates for patients diagnosed with stage I CRC remains above 95%, and identification of patients at this early stage provides the best opportunity to improve in cancer survival rates, recent data has provided quantitative evidence that metastatic seeding can occur from disseminated cells at the very earliest stage of CRC development. The aim of study was to give an insight into aggressive “born-to-be-bad” biology through generation and transcriptional profiling of a novel case-controlled retrospective T1 CRC discovery cohort. We performed transcriptional and histological profiling to identify molecular pathology features of the high-risk metastatic phenotypes, discriminating between relapse and non-relapse T1 lesions and found that a cohort of aggressive early disseminating stage 1 CRC is associated with high cell intrinsic TGFB signalling and not stromal signalling.
